COIN-LOCK FOR WEIGHING-SCALES.

SPECIFICATION forming part of Letters Patent No. 419,544, dated January 14, 1890.

Application filed April 10, 1889. Serial No. 306,679. (No model.) Patented in England March 11,1887, No. 3,730, and August 4,1887,No.10,707. I

To all whom itmay concern: on the arm F, and a disk G, resting against Be it known that I, JAMES MORRIS OKELLY, a collar on said rod F. Said rod F is provided of the city of New York, in the countyof New with a rack H, engaging a pinion H on the York and State of New York, asubject of the shaft H journaled in the casing A, which 5 Queen of Great Britain, have invented cershaft II is provided on its outer end with a tain new and useful Improvements in Coinsuitable pointer for indicating the weight of Looks for WVeighing-Machines, of which the the person on a dial H on the face of the following is a specification. casing. The bar F is also provided with a This invention waspatented in Great Britrack I, engaging a cog-wheel I on the same 10 ain March 11, 1887, No. 3,730, and August 4, shaft j with the sprocket-wheel J, over which 1887, No. 10,707. an-endless chain K passes, which also passes This invention relates to that class of over a sprocket-wheel J. On the top part of weighing devices which are released upon desaid chain K a stepped or oifset block L is positing a coin; and the object of my invensecured, which is adapted to engage a like I 5 tion is to provide a new and improved coinstepped or oifset block L, suspended from lock for weighing devices for the purpose of the end of a lever L pivoted between standlockingthe weighing device in such a manner ards M, projecting from the arms M of the that it cannot be used until a coin is deposcasing. 011 the opposite end of thelever L a ited. coin-pocket N is secured, against the open :0 The invention consistsin the construction side of which the plate N rests, which is seand combination of parts and details, as will cured on the end of an arm N projecting latbe fully described and set forth hereinafter, erally from the top part of the chain K, as and finally pointed out in the claims. shown in Fig. 3. The lever 0, provided at In the accompanying drawings, Figure 1 is its upper edge with a shoulder O, is pivoted 25 a vertical transverse sectional view of a to the arms M, and to the lower end of said weighing apparatus provided with my imlever O a latch O is pivoted, the upper end provement on the line 1 1, Fig. 2.

sponding parts. The operation is as follows: WVhen a person The upright casing A is provided with a drops a coin of the proper weight into the horizontal base portion B, in an aperture of coin-chute, the same passes into the coinwhich the weighing-platform G is mounted to pocket N, in which it is retained by the plate 40 move vertically, said weighing-platform being N adjacent to the open edge of said pocket.

connected with a bent lever O, fixed to said The weight of the coin causes that end of the 0 platform and pivoted to one end of the lever lever L to which said coin-pocket is secured D, fulcrumed at D, the opposite end of said to descend, whereby the block L, suspended lever being pivoted to one end of the lever from the opposite end of the lever L is raised,

45 E, fulcrumed at E. The opposite end of the the lever L being raised to such an extent lever E is pivoted to the lower end of a rod that it can engage and rest on the shoulder F, suitably guided in a guide-arm F of the O on the upper end of the lever O, which casing A, which rod is pressed upward by a thus keeps the lever L in the raised position helical spring G, surrounding it and bearing and prevents the block L from descending when the coin drops out .of the pocket N. The person now steps on the weighing-platform C, and the same descends under the action of the weight of the person, thereby moving the rod F downward and compressing the spring G more or less, according to the weight of the person on the platform. As soon as the rod F descends the spring G is compressed and the upper part of the chain K is moved to the right, whereby the plate N is moved from the open edge of the coinpocket N, permitting the coin to drop out of the pocket, and the lower part of the chain is moved to the left. lVhen the person leaves the platform, the spring G expands and moves the rod F upward, whereby the sprocketwheels J J are turned in such a manner as to move the bottom part of the chain K to the right and the upper part of the chain to the left-that is, the movement of the chain is the reverse of that when the rod F is moved downward by the weight of the person. The parts of the chain only travel a short distance in one direction and the same distance in the reverse direction. The pin or arm P, which is now at the left-hand edge of the latch 0 strikes said latch and swings its lower end to the right, whereby the upper end of the lever O is swung to the left and disengaged from the lever L thus permitting the block L to descend and engage the block L, whereby the entire mechanism is locked. If a person steps on the platform, but has not deposited a coin, the device cannot operate, as the block L would tend to move the block L to the right, this being prevented by the stop Q, against which said block L abuts.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a weighing-platform, of a rod or bar connected with and op erated by the weighing-platform, a chain operated by said rod, a block on said chain, a pivoted lever, a block suspended from one end of said pivoted lever and adapted to engage the block on the chain, and a coinpocket on the opposite end of said lever, substantially as set forth.

2. The combination, with a weighing-platform, of a rod or bar connected with and ope 'ated by the same, a chain ope 'ated by said bar or rod, a block on said chain, a pivoted lover, a block suspended from one end of said pivoted lever and adapted to engage the block on the chain, a coin-pocket on the opposite end of the lever, one edge of which coinpocket is open, and a plate for closing said open edge of the coin-pocket, which plate is connected with the chain, substantially as set forth.

3. The combination, with a weighing-platform, of a rod or bar connected with and operated by said platform, a chain operated by the rod or bar, a block on said chain, a pivoted lever, a block suspended from one end of the pivoted lever, a coin-pocket on the other end of said lever, an additional pivoted lever for holding one end of the lever carrying the coin-pocket in the raised position, a latch pivoted to said additional lever, and an arm on the chain adapted to act on said latch, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my namein presence of two subscribing witnesses.

JAMES M. 'OKELLY.
